Vishwa Rana, a 12th grade student, completed a physics project on a laser security alarm system under the guidance of teacher Shweta Mishra. The project details the components, working, and uses of the system. It functions by using a laser beam to activate a light dependent resistor, which triggers an alarm if the beam is blocked. The system can be used to detect intruders and monitor doors, areas, and property boundaries in a contactless way through the use of laser technology.
LASER BASED DOOR SECURITY SYSTEM USING SIREN GENERATORShahrukh Javed
Â
BRIEF DESCRIPTION:
Door guard is a device that can senses intrusion, providing an indication of possible disturbance, thus providing security to the commercial and residential people.
If some intruder tries to open the door of your house, this circuit sounds an alarm to alert you against the attempted intrusion.
In case of commercial security, little door guard popularly known as guard alarm which provides audible or visual alarm from the detecting object itself.
When any person or object crossover the laser line the security alarm will ring-on also the focus light will "on" to focus the entrance of unauthorized person.
This circuit diagram of a little door guard based on national semiconductor UM3561integrated circuit, siren generator and a laser beam.
The circuit uses readily available, low-cost components. For compactness, an alkaline 9v battery is used for powering the unit. Input dc supply is further regulated to a steady dc voltage of 5v by 3-pin regulator IC7805. Assemble the unit in the box and mount the same on the door & mount a constant source of light i.e., laser beam exactly aligned with the unit.

This is all about the whole system which is capable the count the entry of threats to a particular secured area.
The final product will be the model of "laser security alarm". The project model consists of mainly two parts-
1. laser security alarm
2. person counter
Laser security alarm will notify that someone has trespassed secured area and analog counter will give the count that how many persons have trespassed that particular area.
This project will give us effective protected area to us. Once this protected area will be breached, the alarm will sound.
We made the laser security in low budget. It had been protect in full security. Laser security systems are a high tech technology that used to be a part of home security only available to the wealthy. It is manually switch dependent sensors and a basic alarm unit.
Laser has several advantages as compared to other light sources like cheap, less manpower; efficient, easily available, design is quite easy.

The main aim of this project is to saving system with LDR this is to save the power. We want to save power automatically instead of doing manual. So itâs easy to cost effectiveness. This saved power can be used in some other cases. So in villages, towns etc. we can design intelligent systems for the usage of light or we can also use this to reduce the electricity bill of our home. This project can also be used for security of the houses, banks, etc.
IoT Based Infrared Remote Controlled AC Fan Regulatorijtsrd
Â
This paper presents the design and implementation of an infrared remote controlled ac fan regulator. The regulator consists of IR sensor, monostable multi vibrator, decade counter, transformer, comparator, opto isolator and TRIAC. The user will be able to operate the regulator with any remote control used for TV, VCR, Air Conditioner, DVD player etc. The remote transmits a beam of light and this light is picked and decoded by the receiver unit. The receiver only activates when it receives the beam of light. Every time when the button is pressed, the speed of the fan is increased smoothly up to ten different speed levels. The fan regulator has been simulated and experimentally tested. It is found that the system works satisfactorily and the experimental results are almost same. Details of each unit are described in the paper. Abdullah Al Zubaer | Md. Ariful Islam | Md. Habibur Rahman | Md.

AUTOMATIC LIGHT & DARK SENSING SYSTEM WITH MOSQUITO REPELLENT CIRCUITShahrukh Javed
Â
DESCRIPTION
It is a simple and powerful concept, which uses transistor (BC 547) as a switch to switch ON and OFF the light automatically & a Light Dependent Resistors (LDR) which senses the light, made from a piece of exposed semiconductor material i.e cadmium sulphide, that changes its electrical resistance from several thousand Ohms in the dark to only a few hundred Ohms, when light hits the device, the photons give electrons energy by creating hole-electron pairs in the material. This makes them jump into the conductive band and thereby conduct electricity.
The circuit automatically switches ON lights when the light goes below the visible region & automatically switches OFF lights when light fall on it, by using a sensor which senses the light just like our eyes.
Also, the circuit has a long response time requiring many seconds to respond to a change in the light intensity.

Operation âBlue Starâ is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasnât one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

11. IINTRODUCTIONNTRODUCTION
Security is a most important factor today.Technology develops day by day in
the world.The crime gang also improves their technology toperform their
operation.
So technology of securityshould be modern with time to protect the crime
works.We decide to make a security project as our project. Inthis project
we have used laser light to cover a large area.
We know laser light goes through long distancewithout scattering effect. Itâs
also visible only at sourceand incident point, otherwise invisible.
These two properties help us to build up a modern security system,which may
name as âlaser securityâ.
When any personor object crossover the laser line the security alarm
willringing and also the focus light will âonâ to focus the
entrance of unauthorized person. We can make asecurity boundary of single
laser light by using mirror at every corner for reflection.
13. Experimental SetupExperimental Setup
1) Connect a photocell to a 5K resistor. This will pick up the laser light
and enable the alarm.
2) Use a 2N7000 transistor to link the resistor, a 1uF 63v capacitor, a
5v siren and a 9v battery clip. The attached schematic should
demonstrate how the parts come together. Use an breadboard to
hold them in place and make sure the board is small enough to fit
into a project box. Do not connect the battery yet.
3) Use tape, glue, or strips of velcro to mount the two project boxes
on either side of the door you wish to protect.
4) Connect a 9v battery to the first project box and replace it in the
exact position is was in.
5) Turn the laser on with the toggle switch and make sure it lines up
perfectly with the photo cell. The alarm is now activated. If
anything breaks the beam, the siren will go off.
14.
15. WorkingWorking
1) This circuit is based on LDR (Light Depended Resistor), a variable resistor in which the
resistance varies according to the light intensity falling on it.
2) The LDR and resistor R1 forms a potential divider network, which is the main part of
our security alarm circuit.
3) We have already discussed about how transistor acts as a switch, the same principle is
used here.
4) The voltage drop across the LDR is used to drive the transistor switch. When the
voltage drop is above cut in voltage (0.6V), the transistor is turned ON.
5) LDR has low resistance (mΊ range) in the presence of light and high resistance (MΊ
range) in the absence of light.
6) In our security alarm, a LASER light is allowed to fall on the LDR continuously using 3
mirrors (see the project arrangement figure).
7) Light from other sources should not be allowed to fall on the LDR, so place the LDR in
a box with a single hole to pass LASER.
8) In this situation, the resistance offered by LDR is too low, since the LASER light is
continuously allowed to fall on the LDR surface.
9) Thus the voltage drop across the LDR is also low [V=IR (Ohmâs law)] which is
insufficient to turn ON the transistor, so the transistor remains in OFF state.
10) When a person (eg: thief) makes a block to the continuous flow of LASER beam, then
the light falling on the LDR gets blocked. Thus its resistance increases to a high value
in the order of MΊ range (According to Ohmâs law V=IR).
11) While resistance increases the voltage drop also increases, when this voltage drop
exceeds the cut in voltage of the silicon NPN transistor (2N7000), it will turn ON.
12) Then current from Vcc starts flowing to ground via the buzzer and transistor, which
makes the beep sound.
13) The beep sound from the security alarm gives the indication of some security failures.
16. Uses Of Laser Security Alarm System
1) Laser Security System Locks Working1) Laser Security System Locks Working : Laser door alarm is based on
the interruption of Laser beam. The laser pointer is used as the source of
light beam.
⢠If somebody tries to break the laser path, then an alarm will be generated in
a few seconds. Normally laser door alarm circuit will have two sections.
⢠First one, laser transmitter is a laser pointer readily available. This is
powered with 3 volt DC supply and fixed on one side of the door frame.
⢠The receiver will have a Photo transistor at the front end. We use 2N7000
NPN Darlington photo transistor as a laser sensor.
⢠Here IC1 is used as a voltage comparator with its inverting input tied to a
potential divider R2-R3. We use the inverting input to keep at half supply
voltage.
17. 2) Laser System2) Laser System : Laser technology products will calculate distance by
measuring the time of flight of very short pulses of infrared light. It is
different from the traditional surveying instrument method of measuring
phase shifts by comparing the incoming wavelength with the phase of the
outgoing light pulse.
⢠Solid objects will reflect back a certain percentage of the emitted light
energy. It only needs to be a small percentage for our sensitive detector to
pick it. We can measure the time it takes for a laser pulse to travel to the
target and back with a reflection. By knowing the constant speed of light
we can calculate the distance traveled. It calculate accurate area of house
and protects it from thiefs .
18. 3) Theft Detection by Laser Sytem3) Theft Detection by Laser Sytem : It can be designed as a simple
electronic project for demonstration in science exhibitions. It can also be made
as a mini or major project for electrical or electronic students.
⢠When making this laser security system one can know all about laser beams and
their installation. While preparing a laser security system, we need to
concentrate on the microcontroller program and installed with the laser beam
device.
⢠When using traditional photo resistors for preparing security systems one has
to consider the natural light phenomena. Laser are strong in beam width and can
be focused on the perfect target.
⢠By using laser security system one can
be safe in the case of harmful effects
to the body. As the beam width used in
The laser security systems are not strong
beam widths. Which are used in the
cutting devices.
19. 4)Other Uses Of Laser Security Systems4)Other Uses Of Laser Security Systems : The Laser security systems
are high tech innovations that have gained popularity in home and office
security systems. These are used to be expensive solutions for security
needs. Depending on cost and fast technological advancements laser
security systems becoming more adoptable.
20. ConclusionConclusion
⢠Home security is rapidly growing field and there are new &
improved burglar alarms popping up everyday.
⢠With rapid advancement of technology the filled is turning out
to be an area full of scope and new changes can be made to make
itâs more efficient.
⢠It has years to come, because security is of prime importance to
one and all.
